YB-12-0.4 High Voltage Combined Substation Switchgear(European Type) For Power Distribution

This substation switchgear is a very important power distribution and supply unit in the electrical cable power net. It is a kind of completed set of power supply with High Voltage controlling, protection and converting ,distribution.. it is used in 3 phase AC 50Hz and rated current max 1600KVA transformer. It is widely used in industrial and mining enterprises, residential quarters, hospitals, malls, high-rise buildings, and other distribution systems.
For this substation, we mainly produce & export 11KV, 15KV,20KV,24KV, and 33KV types.
For customized special type, once we get clear technical data or single line diagram(SLD), we also can make it.

1. One of the key advantages of these switchgear is their ability to centralize control and monitoring of the power distribution network. This centralized control allows for easier maintenance and troubleshooting of any issues that may arise.



2. Another important feature of electric power distribution switchgear and substation is their ability to improve the overall reliability of the electrical system. By providing a centralized point for power distribution, these cabinets help to minimize the risk of power outages and ensure a more stable supply of electricity to consumers.

requirements in high-altitude areas.



3. Furthermore, electric power distribution switchgear are designed to be compact and space-saving, making them ideal for installation in various environments. Their modular design also allows for easy expansion and customization to meet the specific needs of different applications .



4. In addition, these switchgear are equipped with advanced safety features to protect against electrical hazards and ensure the safety of personnel working with the equipment. Overall, electric power distribution cabinets offer a reliable and efficient solution for managing power distribution in a wide range of applications.
